For women, the chances of being healthy at age 70 are better for those who do not earn too much weight between 18 and 50 years and are not obese at 50.
This news appears In the "first" online edition of BMJ.
But millions of middle-aged women are overweight and obese, and can not go back in time to change this. Researcher Qi Sun, MD, Department Nutrition at Harvard School of Public Health, do not want these women to give up on the possibility of healthy aging.
"The key message of our paper is that to enjoy a healthy but long life, women They need to maintain a healthy body weight at all adulthood, "says WebMD in an email." Meanwhile, I believe it is never too late to take initiatives to lose weight (safely and healthy) to maximize the likelihood of reaching Healthy survival, "writes Sol.
Sun points out that being physically active, at any weight , It's a healthy habit.
"The bottom line is women who are already 50 years old, no matter the current weight, can still benefit from physical activity to increase your likelihood of having a wonderful health in later life," Sun writes. "Of course, the best way to maximize the likelihood of healthy survival is to maintain at least moderate levels of physical activity and a healthy body weight at all adulthood."
Meal Plan For Women's Weight Loss - Women's Weight Tied to Healthy Aging
The study of the Sun focuses on "healthy survivors". This is the term sun and colleagues brother-in-law for women who studied that they lived at 70 years without any of the following:
Data came from a long-term health study of 121,700 US nurses.
Women answered questions about their height, weight, health and lifestyle every two years for decades, starting 1976, when they were 30-55 years LD.
About 17,000 women were still alive, with sufficient data for the Sun team to study at age 70.
Only 10% of these qualified women as healthy survivors.
Obese women at age 50 were 79% less likely than women with a normal BMI at that age to be healthy survivors.
What happened to the weight of women between 18 and 50 years mattered.
Overweight women (but not necessarily obese) at age 18, and they won at least 10 pounds (about 22 pounds) at age 50, had the worst chances of becoming a healthy survivor. Only 18% of these women have become healthy survivors.
The more weight women earned between the ages of 18 and 50, less likely to become healthy survivors.
The study does not cause women's weight affected their survival. Observational studies, like this, do not cause cause and effect. And it is possible that nurses in the study do not represent all women.
However, the results maintained when the researchers adjusted for these factors: the age of women in the study registration; Education Level; Marital status; Level of husband's education; hormonal use after menopause; smoke; various diet patterns; Family history of heart disease, diabetes or cancer; and physical activity.
